    • US Voluntary Observing Ship (VOS) - International Maritime Meteorological Tape (IMMT) data from SEAS version 9.1 E-Logbook Software

    Metadata Updated: September 19, 2023

    The US Voluntary Observing Ships (VOS) report surface marine observations in both real-time (FM-13 ship format) and delayed-mode (International Maritime Meteorological Tape - IMMT format). To do this, most operating vessels use e-logbook software that allows an observer to enter information, then the software can transmit a real-time report as well as save the same report in a different format to the ship's hard drive for later access, i.e. delayed mode observation (DM). Once in port, all DM reports stored on the hard drive are retrieved and sent to the National Climatic Data Center for archiving and processing. The e-logbook software used in this dataset is the SEAS v9.1 program and structures data in the IMMT-5 format.

    Licence Data are archived by the begin date of data within the file, though data can extend across various years or decades within a file. At this time, if users are interested in a specific year, we recommend that they contact Customer Services or download the entire dataset to ensure that no data is overlooked.
    Lineage Data are original observations recorded via e-logbook software as a delayed mode observation (DM). Files are sent to the NCDC once a ship arrives in port, downloads, and sends the data.
